* The Double Nine Festival occurred on the ninth day of the ninth lunar month. The number nine in Taoism was associated with yang, the male principle, and so it was a masculine festival. A tradition was for men to climb to the heights and sun themselves, the sun being a yang element. It was considered to be good for one's health on the Double Nine to pin a sprig of the cornel dogwood (Cornelis officinalis) to one's gown.
